ROLL-PAPER HOLDER AND CUTTER.

SPECIFICATION forming part of Letters Patent No. 448,113, dated March10, 1891.

Application filed October 18, 1889. Serial No. 327,403. (No model.)

1'0 all whom it may concern.-

Be it known that I, JAMES M. BOLTON, a citizen of the UnitedStatcs,residing at Springfield, in the county of Sangamon and State ofIllinois, have invented a new and useful Stand and Knife for PaperRolls, of which the following is a specification.

The invention relates to improvements in stands and cutting-knives forpaper rolls.

The object of the present invention is to simplify, improve, and cheapenthe construc in accordance with the invention. I Fig. 2 is a verticalsectional View. Fig. 3 is a detail perspective view of thecutting-knife. Fig. 4 is a side elevation showing the normal position ofthe knife, and Fig. 5 is a similar view showing how the knife swingswhen the paper is drawn upon.

Referring to the accompanying drawings by letter, A designates a pair ofvertical standards, which have feet a at their lower ends, that arebolted or otherwise secured to a suitable base or support B. Thestandards are provided at a suitable point, preferably about midway oftheir ends, with upwardlyinclined arms 0, which are provided on theirinner facing sides with grooves c. The

grooves 0' have their lower ends rounded to form journaled bearings andare provided a short distance from their ends with openings 0 that arepreferably arrangedat opposite sides of the arm and permit the journalsor trunnions of acutting-knife D and the shaft which carries the roll ofpaper to be readily inserted and removed from the groove of the inclinedarm. Curved braces E are provided, which connect the standard to theinclined arm, and the standards, braces, and arms are preferably castintegrally; but they may, if desired, be formed separately and securedtogether. The upper ends of the standard are connected by a cross-bar F,which is bolted or similarly secured to horizontal plates at at theupper ends of the standards, the plates being similar in size and shapeto the feet a at the lower ends of the standards. The roll of paper G ismounted on a suitable shaft H, whose journals find bearings in the lowerends of the grooves a of the inclined arms, and the knife or cuttingblade D is straight and has a plain lower surface and has its front edged beveled. It is provided at its ends with integral journals d, whichare inserted in the grooves c. The back of the knife or cutting blade Dis provided at the ends with depending cars (1 which are provided withperforations C1 in which is journaled a cylindrical roller I, which.bears against the paper and holds the front or beveled edge at a tangentto the roll in order to adapt the blade to cut readily the paper whenthe free end of the latter is drawn outward; and in order to prevent thebeveled edge (I swinging out too far from the paper by the blade turningon its journals d the cylindrical roller I has its journals "6projecting beyond the ears (1 of the cutting-blade D and adapted toengage the upper sides of the inclined arms, whereby the rotary movementof the knife or cutting blade on its journals d is limited. The rearedge of the cutting-blade is provided with a depending flange (1 whichis formed integral therewith and with the ears (Z and when it is desiredto prevent the rotation of the roller I to retard the unwinding of thepaper a small plug J, of rubber, is forced between the roller and thedepending flange (1 A projection d is formed at the front of the knifeupon one side to engage the lower edge of one of the inclined arms 0 andto also aid in limiting the swinging or rotary motion of the knife-bladeand hold the latter against the paper when tearinga piece off the roll.As the paper is used and the roll becomes smaller in diameter, the knifewill gradually drop bygravity in the grooves and accommodate itself tothe size of the roll. The knife when desired may be reversed and placedin the lower ends of the grooves, and the paper is then placed above theknife and gradually sinks and approaches the latter as it becomes used.

The inclined arms 0 may be arranged at the top or bottom of thestandards and upon either side thereof, and I desire it to be understoodthat I do notlimit myself to the precise details of construction hereinshown and described, as I may without departing from the spirit of theinvention make various minor changes therein.

From the foregoing description and the accompanyingdrawings theconstruction, operation, and advantages of the invention will readily beunderstood.

Having thus described my invention, what I claim,and desire to secure byLetters Patent, 1s-

1. The combination of the standards having the inclined arms providedwith grooves, the rollof paper journaled in said grooves, the knifeprovided at its ends with integral journals arranged in said grooves,and means for limiting the rotary motion of the knife and holding thesame in proper position for cutting, substantially as described.

2. The combination of the standards havin inclined arms provided withgrooves, the roll of paper journaled in said grooves, and the knifeprovided at its ends with integral journals arranged in the grooves andhaving upon one of its ends a projection adapted to engage the side ofone of the arms to limit the rotary motion of the knife and hold thelatter against the paper, substantially as described.

3. The combination of the standards having the inclined arms providedwith grooves, the roll of paper journaled in said grooves, the knifeprovided at its ends with integral journals and having depending cars (1and a roller journaled in said ears and having its journals projectingbeyond the knife and adapted to engage the sides of the arms,substantially as and for the purpose described. 4. The combination ofthe standards provided with inclined arms having grooves, the roll ofpaper journaled in said grooves, the knife having integral journals andprovided with depending ears (Z and a flange d", a roller journaled insaid ears and having its journals projecting beyond the knife andengaging the sides of the arms, and a plug interposed between the rollerand the flange, substantially as and for the purpose described.

5. The combination of the standards having arms provided with groovesand having openings communicating with the grooves'arranged at theirsides and within a short dis- V tance of their ends, the roll of paperjournaled in the grooves, and the knife provided at its ends withintegral journals arranged in the grooves, substantially as described.

In testimony that I claim the foregoing as my own I have hereto affixedmy signature in presence of two witnesses.

JAMES M. BOLTON.
